Answer: No, it is not at all necessary. In a group, you can be on completely different levels. But this still means nothing. Do not strive to fit yourself under some common measure.
Each person should, as much as possible, positively influence others, unite them, fill them through himself, and most importantly, raise MAN to the Creator from all the friends in the group. In this case, we advance.
We should not compare who is more, who is less. After we come a little closer, we will begin to feel ourselves in a single system—in the ten— where the mutual combination of forces takes place. Therefore, it has everything in common: a common revelation of the Creator, a common light, and a common tension.
And although each of us is different from the rest, one has a higher sensitivity to sensations, the other has a sensitivity to knowledge, etc., but since all kinds of additions and calculations are taking place here, both sensory and physical, these are eliminated in the upper ten, for everyone, everything goes the same way, and for everyone, one Creator is revealed.
